Creating a MultilayerPolygonSymbol using QML rather than json and javascript

PaulHaakma — Fri, 04 Jun 2021 01:29:42 GMT

Can someone tell me how you would go about defining a MultilayerPolygonSymbol using QML?

I have been able to create one using json (created by authoring a symbol in Pro, exporting and ripping it out of the layer file) and javascript, but have struggled to understand how to compose the same symbol using QML.

The symbol is for a polygon and it essentially two symbols, one for the normal polygon outline and another one to place markers on each vertex.

My current way is to do the following:

const customSymbolJson = app.folder.readJsonFile("./Samples/customSymbol.json")
const sym = ArcGISRuntimeEnvironment.createObject("MultilayerPolygonSymbol", {json: customSymbolJson});

Where the json in the json file is:

Moving this to the ArcGIS Runtime group to get more exposure.
